基于RSA算法的加密解密以及数字签名系统，实现加密解密签名的功能(RSA-based encryption and decryption algorithms and digital signature system to achieve the function of signature encryption and decryption )

VB6.0调用Windows系统的API计算MD5码。这个代码跟网上流行的代码相比，具有代码简洁，维护方便，运行效率高等优点。运行速度比用纯VB6实现的快得多。(VB6.0- Call Windows system API calculate MD5 code. This code is compared with the popular online code, with code simple, easy maintenance, high efficiency. Runs faster than pure VB6 realize faster.)

自己开发的一个des加密算法，可用作网络通信方面，希望对大家有帮助(Their development of a des encryption algorithm can be used as network communications, we want to help)

说明：  密码学BM算法的C++实现。可计算100阶m序列的生成多项式(Cryptography BM algorithm in C++. Computable 100 m sequence generator polynomial order)

RSA数字签名的源代码 vc++6.0实现的版本(RSA Digital Signature vc source code version 6.0)

3Des encryption of text from a file, 3DES-EDC-CBC , using 3 keys

C++ implementaion for RSA together with the Wiener attack. It uses NTL library for big numbers

我自己编写的rsa算法，实现了加密和解密功能

加密程序,很好用。亲自验证，完全正确。希望下载。(we can add and unadd a picture correctly.welcom to download.)
